Fail to cross compile arrow_cpp in rerun_cpp_sdk

[SunDoge]

Describe the bug

Fail to cross compile rerun_cpp_sdk to aarch64.

In arrow_cpp-configure-out.log

-- System processor: x86_64
-- Performing Test CXX_SUPPORTS_SSE4_2
-- Performing Test CXX_SUPPORTS_SSE4_2 - Failed
-- Performing Test CXX_SUPPORTS_AVX2
-- Performing Test CXX_SUPPORTS_AVX2 - Failed
-- Performing Test CXX_SUPPORTS_AVX512
-- Performing Test CXX_SUPPORTS_AVX512 - Failed
-- Arrow build warning level: PRODUCTION
-- Configuring incomplete, errors occurred!

And arrow_cpp-configure-err.log

CMake Error at cmake_modules/SetupCxxFlags.cmake:472 (message):
  SSE4.2 required but compiler doesn't support it.
Call Stack (most recent call first):
  CMakeLists.txt:415 (include)

To Reproduce

I am unable to provide reproduction steps as I am using an internal system.

Expected behavior

Can be fixed by adding -DCMAKE_TOOLCHAIN_FILE=${CMAKE_TOOLCHAIN_FILE} to download_and_build_arrow.cmake

-- System processor: aarch64

You should modify the download_and_build_arrow.cmake script to include the -DCMAKE_TOOLCHAIN_FILE=${CMAKE_TOOLCHAIN_FILE} option This will ensure that CMake uses the correct settings for cross-compiling to aarch64

our CMake files are generally not set up and tested for cross compilation right now. But please do try @PrasanBora 's suggestion. If it works a doc update PR would be in order :)

I have already tried it before and it works. I open this issue because I hope -DCMAKE_TOOLCHAIN_FILE=${CMAKE_TOOLCHAIN_FILE} can be added to the official repo so I don't have to patch it.

@SunDoge if that's all there is to it, would you mind opening a PR? :)
